By using graphical representations of simple portfolio choice problems, we generate a very rich dataset to study behavior under uncertainty at the level of the individual subject. We test the data for consistency with the maximization hypothesis, and we estimate preferences using a two-parameter...

We utilize graphical representations of Dictator Games which generate rich individual- level data. Our baseline experiment employs budget sets over feasible payoff- pairs. We test these data for consistency with utility maximization, and we recover the underlying preferences for giving...
